2.5 Functional Description
The P16800 is available in 1 and 2-channel versions and is used to detect speed sensor signals. The in-
put of the P16800 is designed in such a way that speed sensors with current or voltage output can be
connected. The outputs of the product can be configured as current or voltage outputs and behave
like a speed sensor for the controls.
P16810
1 input, 1 output
P16820
2 inputs, 2 outputs
P16840
2 inputs, 1 output, 1 DOT output
• The P16800 transmits galvanically isolated the pulse signal from speed sensors from the input to
the output. The product is used to double signals, i.e., to decouple them from existing measuring
circuits, or to protect controls from voltage loads on the speed sensor.
• P16840 only: The product can detect the direction of rotation of an axle or the direction of travel of
a vehicle.
• In the absence of input pulses, the product can detect the standstill of an axle or a vehicle.
• The reinforced insulation according to EN 61140 ensures protective separation, and the protection
of persons from electric shock.
• The galvanic isolation protects the equipment and contributes to an unaltered transmission of the
measuring signals. This may improve the signal quality and decouple the controls.
EMC interference at the controls can thus be reduced.
• The P16800 can process signals from speed sensors and other pulse transmitters, e.g., flow sensors.
• The P16800 detects the pulse signals from speed sensor circuits without influencing them.
The absence of interaction can optionally be set for safety-related applications up to SIL 4.
• The pulse transmission from the input to the output can optionally be set for safety-related
applications up to SIL 2.
• Pulse transmission can be set as 1:1 or, with frequency division, as 2:1 (4:1 or 8:1 available ex
works). With enabled frequency division, the output signal has a pulse-pause ratio of 50 %.
• The pulse signals can be inverted.
• The speed sensor’s voltage supply U
S
at the input of the P16800 is required in order to set the
switching threshold during operation. U
S
is not used to supply the P16800.
• The output is the binary image of the input signals (high/low level).
• The compact enclosure is suitable for mounting on 35-mm DIN rails and walls
(ZU1472 wall-mount adapter, optional
• The following SIL products are suitable for safety-related applications:
◦
SIL: P16811, P16812 in 1-channel version
◦
SIL: P16821, P16822 in 2-channel version
